Three Expeditions into the Interior of Eastern Australia | Page 8

Balyran, and, on approaching the sea, he had seen a burning mountain named Courada. He described, with great apparent accuracy, the courses of the known streams of the northern interior which united, as he stated, in the Namoi, a river first mentioned by him; and, according to his testimony, Peel's river entered the Namoi by flowing westward from where Mr. Oxley had crossed it.
Now this was contrary to the course assigned to the Peel in the maps by early travellers, but consistent nevertheless with more recent surveys. Vague accounts of a great river beyond Liverpool plains, flowing north-west, were current about the time General Darling embarked for England. The attention of the acting governor, Colonel Lindesay, was particularly drawn to the question by this report of Clarke, and also by the subsequent proposals of various persons, to conduct any expedition sent in search of the great river.
PLAN OF EXPLORATION.
There are few undertakings more attractive to the votaries of fame or lovers of adventure than the exploration of unknown regions; but Sir Patrick Lindesay, with due regard to the responsibility which my office seemed to impose upon me, as successor to Mr. Oxley, at once accepted my proffered services to conduct a party into the interior.
The principal object of my plan was the exploration of Australia, so that whether the report of the river proved true or false, the results of the expedition would be, at least, useful in affording so much additional information; equally important geographically, whether positive or negative.
After I had surveyed extensive tracts of territory I never could separate the question respecting the course of any river from that of the situation of the higher land necessary to furnish its sources and confine its basin. I could not entertain the idea of a river distinct from these conditions, so necessary to the existence of one; and it appeared to me that if a large river flowed to the north-west of any point north of Liverpool plains its sources could only be sought for in the Coast Range in the opposite direction; or to the eastward of these plains.
Various rivers were known to arise on that side of the Coast Range; the streams from Liverpool plains flowing northward; the Peel, the Gwydir, and the Dumaresq, arising in the Coast Range, and falling, as had been represented, to the north-westward. I proposed therefore to proceed northward, or to pursue such a direction as well as the nature of the country permitted, so that I might arrive, on the most northern of these streams, and then, keeping in view whatever high land might be visible near its northern banks, to trace the river's course downwards, and thus to arrive at the large river, or common channel of all these waters.
The second condition necessary to the existence of a river, namely, the higher land enclosing its basin, might, in this case, have been either Arbuthnot's Range, or that between the Darling and the Lachlan; and this seemed to me to involve a question of at least equal importance to that of the river itself, for, had the fall of all the waters above-mentioned, been to the north-west, it was obvious that such a range must have been the dividing ridge or spine connecting the eastern and western parts of Australia, and which, when once investigated was likely to be the key to the discovery of all the rivers on each side, and to the other subordinate features of this great island.
Thus, the most direct and practical plan for seeking the river, was perfectly consistent with my views of general exploration.
PREPARATION FOR THE SURVEY.
In the selection of men to compose an exploring party, and in collecting the articles of equipment, provisions, and means of transport, my department afforded various facilities. This aid was the more necessary in my case, because the other duties of my office, prevented me from devoting much attention personally, to the preparations for such a journey.
From the known level character of the interior, I considered that the light drays or carts used by the surveyors might easily pass, and I therefore preferred them to packhorses, being also a more convenient means of conveyance; I availed myself likewise of such men, carts, bullocks, and horses, as were disposable in the survey department at the time. The new Governor was expected in the course of a few months, and I was therefore desirous to set out as soon as possible, that I might return before his arrival.
After several weeks of anxious preparation, I had the satisfaction to find that every contingency was, as far as possible, provided for in my department. Each officer, whether employed in the survey of the different parts of the colony, or the measurement of farms, was also fully instructed respecting his duties during my contemplated absence.
